- Lou, [ᦗ]

Appearance: Nolan has pale skin, even slightly more so than the others. He has heterochromia iridis (Iritis)—a green eye on the left and a violet eye on the right. His hair is dark brown with a green streak in his bangs that falls over his eyes. He has uneven freckles scattered across his cheeks. Like all the dolls, Nolan wears a school uniform, but his sleeves are long, his vest is sloppily worn, slipping off one shoulder, and his tie is awkwardly tied. He also doesn't wear socks like the others.

Character: He's a rather shy doll who doesn't live up to Lou's standards. He's rather quiet due to his lack of friends. Nolan is the most unique doll, besides Lou, at the Institute for Perfection. His awkward appearance and imperfections make him a unique doll. "Not being perfect makes him perfect."

Appearance: Lou is a puppet in the form of a young man, aged between 16 and 25. He has a typically "Aryan" appearance: he has fair skin, blond hair, and blue eyes, but despite his hair color, his eyebrows are brown, almost black. He also has a short hairstyle combed to the right side. While all the other students wear school uniforms, he wears an elegant black two-piece suit with two gold cufflinks and a purple checkered tie, along with black business shoes.

Character: In his first appearance, the antagonist is presented as a blunt and rude character, reminiscent of a popular school bully. He mercilessly calls every doll ugly, but by the end of the concert, he politely explains to the Uglydolls that they are not meant for the Big World, suggesting he's trying to be sophisticated. However, during his backstory, it's revealed that when he first arrived at the institute, Lou was more beautiful than any doll, both physically and emotionally, a trait that is further revealed through his friendship with Ox: while the other students simply turned away from the imperfect doll, Lou showed greater compassion, becoming Ox's best friend and trying to help him become a better person so he could see the Big World. Even Lou's face then reflected his love for all living things. Over the course of Ox's construction of Uglyville and the time the main characters settled there, Lou became increasingly inhumane. The thought that all his students would replace each other, nullifying the idea of ​​a long-lasting friendship between them and the prototype, Lou stopped seeing the point in any moral compass and drowned out any pity for those who would eventually leave him, and due to the fact that Lou would never see the world of people just because he was forced to mess around with other dolls, he began to hate them altogether. Lou was created as a prototype for the Model 12 dolls, his job is to help the dolls become like him, which speaks of his physical and moral superiority over others.
